The following equation represents the relationship between hours of TV watched per day (x) and the number of situps a person can do (ŷ). ŷ = -0.944xx+ 24.52 Use this model to predict the number of situps a person who watches 6.5 hours of TV can do. (to 2 decimal places)

(0.061)x (0.43)

After I distribute 12.5 throughout the equation,  can you break down the steps before I graph

Let a population consist of the values 9 ​cigarettes, 10 ​cigarettes, and 20 cigarettes smoked in a day. Show that when samples of size 2 are randomly selected with​ replacement, the samples have mean absolute deviations that do not center about the value of the mean absolute deviation of the population. What does this indicate about a sample mean absolute deviation being used as an estimator of the mean absolute deviation of a​ population? Calculate the mean absolute deviation for each possible sample of size 2 from the population. Sample Mean Absolute Deviation   ​{9,9​}     ​{9,10​}     ​{9,20​}     ​{10,9​}     ​{10,10​}     ​{10,20​}     ​{20,9​}     ​{20,10​}     ​{20,20​}
